Now I do the following: - Load a bitmap in my code, copy it to clipboard (Clipboard.SetImage(bmp)), paste it in Excel and manually resize it to half the size- Then in my code use the above function to resize the bitmap to half the size, and then copy it in ExcelAs expected, the bitmaps are exactly th same size, so the resizing works fine. But the bitmap that I resized manually in Excel has a much better resolution! How can I get the same resolution through code?Thanks for your help,Charlie
